I ROLLER MECHANISM.

Application filed March 25, 1922. Serial No. 546,608.

To all whom it may concern:

, Be it known that I, EDwAnD F. DnnLnY, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller Mechanism, of which the following is a Specification.

This invention relates to printing presses and more particularly to an inking and dis .tributing roller arrangement.

One object ofthe invention is to provide a simple, reliable and efficient inking and roller arrangement in which the various parts cooperate inan improved manner.

- Another obj ectis to provide an inking and roller arrangement in which the parts are accesible and convenient, requiring no special adjustments.

These and other objects areaccomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in which i a Figure 1 is a fragmentary front elevation of a printing press embodying my invention; 7 Figure 2 is a fragmentary side elevation of the same with the rollers located in operative position;

Figure 3 is an enlarged sectional View similar to that shown in Figure 2 taken in the plane of line of Figure 1,7and showing the rollers in a general vertically operative position and in a general horizontally inoperative position;

' Figure [i 1s a sectional view taken inthe plane of l ne l'4c'of Figure 1, and showing means whereby the virbrator'roller brackets may pivot an increased amount over the ink- 1ng roller brackets for insuring separation position;

Figure 5 1s a detail sectional view taken in the plane of line- 5-5 of Figure 2, andshowing the locking mechanism; and,

Figure 6 is a detail sectional view taken in the plane of line 66 ofFigure 5.

The various novel features of the invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.

- Referring to the figures of the drawings, it will be noted that I have disclosed my invention in connection with a vertical type of printing pressin which the type bed 10 and the cylinder 1 1 with its frame 12 are reciprocated l siinultaneonsly in opposite direotions. There are two composition or ink distributing rollers 13 and 14;, which, when in operation, are engaged by an ink distributing or vibratory roller 15. The inking rollers 13 and 1a are both mounted in oppositely arranged brackets 16,- both of which brackets 16 are loosely'mounted upon a shaft 17. Each of the brackets 16 is provided with a keyway 18 which is wider than, and receives, a key 19 in the shaft 17, so that the brackets 16 may have a slight relative rotative movement with respect to the shaft 1'7, the purpose of which will appear later. The vibrating roller ismounted in oppositely arranged brackets 2-0 located outwardly from the composition roller brackets 16, said vibrator roller brackets 20 being secured to the same shaft 17 by pins 21. Ac-

cordingly, the vibrator roller brackets 20 have no relative rotative movement with r spect to the shaft 17..

When the machine is not in operation and the rollers are to remain idle for any length of time, or if it is desired to clean such rollers, the same are moved from their operative position into their inoperative position, as shown in Figure 3 of the drawings, in which figure it will be noted that the inking rollers 13 and 1a are in operative position when vertically alined and in inoperative position when horizontally alined. Then the rollers are in inoperative position itis arresting the brackets 16 and the inking rollers 13 and 14 against further downward movement. However, it will be noted that the vibrator roller 15 and its brackets 20 may continue to swing downwardly to permit the vibrator roller 15 to move out of engagement with the inking rollers 13 and 14in view of the fact that the slots 18' in the brackets 16 are wider than the key 19. The extent of separatmg movement of the vibrator roller 15 with respect to the inking rollers 13 and 14 may be any; desirable amount, it being made suffic ent, however,

to separate them only to the extent that it 1 becomes easy to clean such rollers while out ot' engagement with each other. Furthermore, it is desirable to separate such rollers to prevent ridges of ink being formed thereon as a result 01'? such rollers standing unused for a. relatively long time during which time ink is permitted to dry thereon.

IVhile it is desirable to have these rollers separated when not in use, it is likewise desirable to have such rollers firmly locked in engagement with each other and prevent any lost motion therebctween when the are in operative position. To accomplish this result the ink distributing roller is moved into engagement with the inking rollers 13 and l-t, the extent or intimacy of the engagement being limited by stop but-tons 2t on the brackets engaging corresponding stop buttons on the brackets 16, best shown in Figure 3 of the drawings. IVitli the vibrator roller 15 thus in contact with the inking rollers 13 and 14. and with the latter in engagement with the type, or in the proper position to engage the type when the latter is moved during an inking operation, such rollers are locked in position by locking members 26 which are moved into and out of locking engagement with locking pins 27 carried by and extending outwardly from the brackets 20 in which the vibrating roller 15 is mounted. More specifically, it will be noted that the locking member 26 has a semi-circular flange 28, best shown in Figure 6, which is adapted to embrace or surround one side of the locking pin 27 when the rollers are in locked posi tion and which may be moved to the opposite side of the pin 27 when it is desired to release such rollers and their brackets from operative position. These locking members 26 are located at opposite sides of the press on the cylinder frame 12, and for actuating the locking members 26 crank handles 29 are provided.

According the inking and vibrating rollers may not only be locked in engagement with each other and in an operative position, but may be readily released to move into an inoperative position and out of engagement with each other. Furthermore, the inking rollers 13 and 1-1- and the vibrating roller 15 with their brackets and the supporting shaft 1? may be removed as a unit from the cylinder frame by virtue oii the fact that the outer lower sides oi the distributing roller brackets 20 are provided with slots 30 (see Figures 3 and which cooperate with projecting members 31 extending laterally from the cylinder frame 12. These projections preferably provided with tiatened sides to permit slidable engagement between such projections 31 and the slots 30 during the application and withdrawal ot the roller unit herein above mentioned. It will be noted by referring to Figure 3, that the slots 30 are arranged at an angle with respect to the vertical, thereby making it necessary to swing the rollers out ot the vertical operative position to withdraw and apply the unit. The inner ends of the projection 12 are slightly tapered to facilitate applica tion and withdrawal of the roller unit.

Itis my intention to cover all modifications of the invention talling within the spirit and scope of the following cliams.

I claim:

1. In a printing press, the combination of an inking roller, a vilin'ating roller, bracket means in which saidinking rollerismounted bracket means in which said vibrating roller is mounted, and a shaft upon which both of said bracket means are mounted, one of said bracket means having a lost motion connection with said shaft in a manner to permit said rollers to move out of engagement with each other.

2. In a printing press, the combination of an inking roller, a vibrating roller, a shaft, a member carrying said vibrating roller and mounted on said shaft, a member carrying said inking roller and mounted on said shaft, one of said members having a lost motion connection with said shaft to permit a relative movement therebetween for moving said rollers into and out of engagement with respect to each other.

3. In a printing press, the combination of an inking roller, a vibrating roller, a shaft, a member carrying said inking roller and having a lost motion connection with said shaft to permit a relative rotative movement with respect thereto, a member carrying said vibrating roller and mounted on said shaftin non-rotative relationship with respect thereto whereby said inking roller and vibrating roller may be moved into and out of engagement with respect to each other.

l. In a printing press, the combination of an inking roller, a vibrating roller, a support, a member in which the inking roller carried and mounted on said support, a member on which said vibrating roller is mounted and carried by said support, one of said members having a slot adapted to cooperate with a part of the printing press for permitting the application and removal of the rollers, members and support as a unit with respect to the printing press.

In a printing press, the combination of an inking roller, a vibrating roller, a unitary support for said rollers in which there are relatively movable parts whereby said rollers may move into and out of engagemci'it with respect to each other, and single means for locking said rollers when in an operative position.

6. In a printing press, the combination of an inking roller, a vibrating roller, a common support for both of said rollers, means connecting said rollers with said common support whereby said rollers may have a relative movement lnto and out of egagement with each other, and single means for looking and releasing said rollers when in an operative position. y

7. In a printing press, the combination of an inking roller, a vibrating roller, a common support for both of said rollers, means connecting said rollers with said common support whereby said rollers may have a relative movement into and out of engagement with each other, and means for locking said rollers in a given position, one of said rollers belng locked 1n position through the other being locked.

8. In a printing press, the combination of an mking roller, a vibrating roller, a shaft, means carrylng said inking roller and having a lost motion connection with said shaft,
